“…Many of these substances have been detected, not by their action on the microbes, but by their effect on heterologous erythrocytes. Natural antibodies to sheep and rabbit erythrocytes have been observed in teleosts (Cushing & Durall 1957; Sindermann & Krantz 1968; Giclas, Morrison, Curry, Laurs & Ulevitch 1981). Recently, several teleost species have been found to possess haemagglutinins of a lectin‐like nature in their sera against homeothermic vertebrate erythrocytes (Dash, Saha, Sahu & Gangal 1993).…”

This study was carried out to test the effects of acute stress on the primary and the secondary antibody responses in Atlantic salmon (Salmo salar L.). Fish received a primary immunization with sheep red blood cells (SRBC) and received a second immunization 11 weeks later. At priming, a group of fish was stressed by water level reduction for 30 min (moderate stress), and another group was stressed severely by applying the stressor twice, with an interval of 6 h, 3 days in a row (severe stress). At the time of the booster, another two groups of previously unstressed, primed fish were treated likewise. Unstressed fish mounted a primary antibody response to SRBC and a secondary response, which was improved compared with the primary response., The primary antibody response against SRBC was impaired by severe, but not moderate, acute stress at priming, whereas the secondary antibody response was unaffected. Both moderate and severe stress at the time of the booster was immunosuppressive in fish that had been primed under non‐stress conditions. It is concluded that cortisol release as a result of stress exposure is most immunosuppressive at the time of the second immunization.

“…Naturally-occurring bacterial agglutinins and red blood cell haemagglutinins have been reported in a vast range of fish from the marine elasmobranchs (Rudikoff, Voss & Sigel, 1970;Sigel, Voss & Rudikoff, 1972;Sindermann & Honey, 1964) to the teleosts (Evelyn, 1971;Sindermann & Krantz, 1968). It has also been shown that the phylogenetically primitive hagfish (E. stoutii) possesses natural agglutinins for a variety of red blood cells and also to sea urchin spermatozoa (Linthicum, 1971 ;Linthicum & Hildemann, 1970).…”

The primary immune response of brown trout (Salmo trutta L.) was studied after injections of two cellular antigens-Salmonella typhi H, flagellar antigen d, and human group ' 0 ' Rh+ red blood cells. Both intraperitoneal and intramuscular injections were employed. Agglutinins and complement-fixing antibodies were produced to S. typhi and haemagglutinins to human ' 0 ' red blood cells. Maximum titres to S. typhi were reached after 49 days in the case of both agglutinins and complement-fixing antibody. Haemagglutinins reached a maximum value of 1 : 512 between 35 and 42 days. Haemagglutinins to human ' 0 ' red blood cells were detected as early as 7 days after injection. Antibodies against S. typhi were found after 14days. Natural haemolysins were present against horse, sheep and human groups ' A ', ' B ' and ' AB ' but not with group ' 0 '. No natural haemagglutinins were present to the six types of red blood cells tested. No precipitins were detected to either S. typhi or human ' 0 ' red blood cells by immunodiffusion.

“…Agglutinins to homologous RBC (isoagglutinins) have been found in both freshwater and marine teleosts (Cushing & Durall, 1957;Lukyanenko, 1964;Sindermann & Krantz, 1968) and in elasmobranchs (Sindermann & Honey, 1964).…”

Natural 'antibodies' are substances found in the blood of animals that have not been immunised against infective agents. However, exposure to these agents or to cross-reacting antigens may well have taken place. Fish contain naturally-occurring, relatively nonspecific, lectin-like proteins or glycoproteins, which are distinct from immunoglobulins, and which react with a wide variety ofantigens and may confer some degree of immunity against natural infection. In most cases the cause of the antigenic stimulus is not obvious although the formation of these 'antibodies' may have been brought about by exposure to various micro-organisms. Many of these antibody-like molecules behave in a similar manner to immune antibodies or immunoglobulins and cross-react with specific carbohydrate moieties on the cell walls of bacteria, erythrocytes and certain other cellular antigens, due to the presence of similar antigenic determinants.It is difficult to ascribe an appropriatc dcfinition to the term 'natural antibody'. In fish, thesc 'antibodies' have been so designated on the basis of functional rather than structural criteria. Such naturally-occurring, low grade, antibody-like ' immune ' substances include 'acute phase' proteins, lysozyme and chitinase, interferon, agglutinins, lysins, complement and properdin, precipitins, and non-immunoglobulin, lectin-like molecules. In addition to the above non-immunoglobulin materials, natural immunoglobulins identifiable as IgM have also been reported in fish. Furthermore, mucus contains many biochemical agents capable of reaction against infective organisms and thus providing the host with an immediate or a first line of defence mechanism.This review compiles some of the relevant information in the literature concerned with natural 'immune' substances, present in the serum and mucus of fish, involved in protection against pathogens. Wherever possible the basic physicochemical properties of these substances are indicated and their potential immunobiological functions discussed.
